RF Mixers Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm that the 16-TSSOP package matches the target PCB footprint. Ensure the operating temperature range meets system requirements. Validate compatibility with existing RF design parameters given the discontinued status.

RF Mixers Selection Notes

Select this component specifically for legacy CATV designs requiring a 50-280 MHz down converter. Consider the 20 dB gain and 10 dB noise figure against system link budget requirements. Evaluate the TSSOP-16 package constraints for thermal and spatial limitations in the final assembly.

RF Mixers Part Context

The SN761688 belongs to the SN761688 series of down converters from Texas Instruments. It is distinct from other TI logic or data converter families. This specific part number denotes the plastic TSSOP variant, differing from ceramic or other package options if available in the broader family history.

RF Mixers Replacement Considerations

The product status is listed as Obsolete. No public confirmed substitute part numbers are provided in the source documentation. Designers must evaluate alternative components or redesign based on current availability.
